First off, hello everyone! I am new here, and I've been reading several things on this site and uboachan.net and I felt it be high time that I finally make an account.

Alright, with formalities done and over with, I have been thinking about the numbers and the symbols on the apartment walls (the orange and black graffiti in apartments 1 and 2 respectively). I think they have some meaning and are not there at random, especially considering the glitch event when you talk to the wall in one part of the game.

Please note, there are spoilers below:

Now, something makes me think that maybe these numbers could be something in relation to an event that happened. I tried to think maybe they were dates just jumbled up, but I don't know… it's not a price, because I was thinking that maybe certain numbers were references to either a 'sit down fee' to talking to a girl in a snack bar or a prostitution fee, however, the numbers that appear: 3792 and 4231, they do not appear to be the prices that'd validate that theory when converted to yen (or even USD).

In order of event:

1) When going through the hallway of Apartment 1 and going up the stairs, 3792 appears in orange writing. An orange smiley can be found nearby on the wall as well, with a strange sock-puppet looking drawing in orange (which, I believe to be a crude, childish depiction of an erect penis). A puddle of blood is on the floor, and an orange smilely blob is near the number. 4231 in black is on the floor, with a black 'XD' next to it. When you walk up the stairs to the roof, 4231 is written in black with a black 'XD'.

2) Apartment 2 roof has a black 'XD' above the door to go down, and it leads to a room where the orange 'penis' drawing with smiley is on wall. Another blood puddle on ground, and a black 'XD' on ground with 4231 written in black. Orange 'penis' with smiley appears again with a black 'XD', and then 37 is written in orange with an orange smiley with black 4231. Then yet another orange … jesus christ, I really think it's a weird 'penis' drawing… with smiley… Then a bloody pool and orange 37 with orange smiley and then another orange penis with smilely next to orange smilely and orange 3792 with an orange circle with dot and then an orange 92 with an orange dot with circle and a black 'XD'

However, an important connection: Further down is the room with the cone belonging to what looks like a friend of hers that you also cannot reach in the brothel region of a certain hotel.

My question: How do these numbers tie in? They obviously have some sort of meaning, and I think the colors might have some sort of distinction that separates events, just like how Apartments 1 and 2 may either be a lapse in time, or representative of either another apartment or another part of Apartment 1.

Now, since I personally believe that Sabi might have been roped into prostitution after being raped (I can provide the details from the game that make me think this if anyone's interested), I think that these numbers are very, very important to her and tie into important events.

Hello Izzy,
I'm also new here, as I thought these forums weren't used much. Then again, it's been a very long time since I visited this website. I saw your post and decided to join to reply to you.

Anyways, I believe the numbers that you're referring to, are actually 97920 in that order, as opposed to your interpretation from the drawings on the walls in the apartments. While I can see why you'd think that first 9 is a 3, my first thought was that it is a 9, but had been drawn differently when compared to the second 9. Later, when a newer version of .flow had been released, the 'talk to the wall' glitch event had been added in, and the numbers that show up, are definitely 97920. I'll include pictures at the end if I learn how to.

Now, going off of theories from those numbers, I interpreted 97920 to resemble a date in time. Some countries use this date format, including Japan. The numbers, in that particular order, make out to be the 20th day of Sepember, 1997, and assuming that this date refers to Sabitsuki's birthday, it would make her twelve-years-old if you go by the first original release of .flow in 2009. Considering the game didn't develop much until the .10 version, which was released in 2011, she could have possibly been fourteen-years-old by then.
Further support of this, would have to be the event hidden behind the poorly drawn orange phallus with the smiley face, which can be interpreted as an erect penis, as it is 'happy' with a smile. After beating it with the pipe, you'll reveal what is hidden away, and eventually come across the 'dying girls' event. Notice how there are nine regular sized black-haired girls, and one huge one mounted on the wall. One-by-one, each girl dies. When the ninth girl dies, the stomach of the giant black-haired girl errupts and bloodied 'objects' pool onto the floor. Also notice how this event 'activates' when Sabitsuki walks in, as if she had caused it. The nine regular sized black-haired girls can represent nine months, and the giant black-haired girl on the wall can represent Sabitsuki's mother, and the erruption of her bloated stomach represents how Sabitsuki's birth inevitably killed her mother. The look on the giant black-haired girl's face during and afterwards can represent that she might have been suffering from the illness as well, which she might have passed on to Sabitsuki. Proof of this is, in the 3 different hospital corridors, one of them holds a black-haired girl in the corner room [with Little Sabitsuki absent from the middle room] and in the second, the black-haired girl is absent [while Little Sabitsuki is in the room next door], and finally, the third one holds the little red dot in the corner, where the black-haired girl's room would have been, and as Rust, you find that it leads to the same giant black-haired girl in the 'dying girls' event, already dead after her stomach errupted in the Sabitsuki chapter. All of the black-haired girls, for the most part, are located in and around the "Flesh Walls" world, and the map appears to resemble a uterus…
Taking all of these things into consideration, I assume that, on September 20, 1997, Sabitsuki was born, and her mother, the black-haired girl, died in the process of giving birth to her.

As for everything else you question, I'm uncertain of the color scheme and whether or not it holds any meaning. I'll have to look into that some more sometime.

PS: I'm unable to add the pictures since I'm not allowed to use 'links' for some reason. One picture is from the glitch event with the 97920 displayed, and the second is just of the apartment walls that resemble the same number.

EDIT: Another specific area for the black-haired girls to appear, aside from the Flesh Wall world and the hospital areas, is the city, inside of a building that resembles a hotel. I believe that Sabitsuki's mother, the black-haired girl, might have been into a prostitution ring, hidden 'discretely' in the guise of a hotel in the center of the shady yet lively neon city when you travel through the alley. The black-haired girl, being a prostitute, came in contact with many different shady men on a daily basis, and somewhere along the line, contracted a deadly disease that might have overcome the prostitution ring.
While I don't at all deny that Sabitsuki herself is a victim of sexual assault, I definitely know that her mother might have been, which led for her to find a way to make money by serving as a prostitute in this shady, likely gang affiliated ring. A new event within this area reveals a new world which supports the prostitution ring theory, and deep into that world lies a secret: a more innocent, foreshadowing side of perhaps one maid in particular.
